Volunteers try to save trapped fish in Italy
STORY: Tench, catfish and carp used to overwinter in the canals or pools of the Po tributaries such as Orchetto, where the water temperatures are higher than in the Po, were trapped in the shallow waters with a shortage of oxygen.
The absence of oxygen was caused by the high consumption of the fish themselves that are trapped in this channel, and not by chemical pollutants, as reported by Regional Agency for Environmental Protection (ARPA), which carried out initial analyses of water samples in laboratories.
According to ARPA, the scarcity of water caused by the summer drought has reduced the number and depth of natural pools in the river, reducing the number of winter refuges for the fish, making them overcrowded.
